Mod that enables fast spreading of grass/flora after toxic fallout?

[paul23]

Well as per title: after a volcanic winter/toxic fallout my whole map is one brown mass and utterly annoying to play.

In the past I've used "lush meadow" to enable fast spread of the greenery, as it allows spreading of grass in the middle of the map instead of just the edges. However the mod lush meadow hasn't updated since 1.1 and now actively crashes the game.

So is there a variant I could play? How do you solve the "perpetual brown maps"?
